First, the principle of led backlight board
LED emits light, and the electric light source is changed into a surface light source with a light equalizing plate. Compared with the traditional CCFl backlight, it has the advantages of no high voltage (3.3V), long service life (above 100Kh), environmental protection (no mercury), no fear of vibration (no fragile lamp), no damage (as mentioned above), and better backlight uniformity (this depends on the light equalizing plate, but in principle, the light equalizing effect of multi-electric light sources is stronger than that of linear light sources).
Second, led backlight board manufacturers
1. Shenzhen Xinwanheda Electronics Co., Ltd. is a diversified general taxpayer enterprise integrating design, production and sales. Is a high-tech enterprise with photoelectric factory and electrical products factory, mainly engaged in LED backlight /LED light guide plate /LCD backlight /LED luminescent film /TFT backlight board, with daily production capacity of 100000PCS, fast and flexible delivery, and the production environment is purification workshop. We not only have engineers who have been engaged in photoelectric product development for many years, rigorous and efficient modern management system and an innovative team, but also have a group of young and excellent production teams, sales teams and after-sales service teams, which provide a strong guarantee for the development of enterprises. The company has established a quality assurance system according to ISO and 5S standards.
2. Shenzhen Xinyuan Crystal Technology Co., Ltd. is a private enterprise specializing in the design, production and operation of liquid crystal display (LCD) and module (LCM) and LED backlight.

Product advantages, look forward to common development with friends from all sides.
The above small series mainly gives the principle knowledge of led backlight panel manufacturers, and finds that there are many manufacturers that can provide similar products on the market, and there are also many corresponding products. The choices faced by everyone and the troubles that may be encountered during the purchase process are also worthy of attention. Therefore, Bian Xiao gave the above description through the recommendation of professionals, and it can be clear that the qualified led backlight board should be a product with the advantages of low power consumption, low calorific value, high brightness and long life.
